dc.description.abstractSeasonal growth pattern and reproductive biology of the black goby, Gobius niger (n=568; 2.1–14.6 cm TL), were monthly studied in southern Black Sea between December 2012 andNovember 2013. The seasonal von Bertalanffy growth parameters, computed from ELEFAN,were estimated as L∞= 11.9 cm TL, K= 0.701 year-1, C= 0.633, and WP= 0.492 for the Hoenigseasonal model and as L∞= 12.1 cm TL, K= 0.680 year-1for non-seasonal von Bertalanffy model.The size at sexual maturity (Lm) was estimated as 8.9 cm TL. The Gonadosomatic index (GSI)ranged between 0.60 in December and 8.57 in April 2013 (mean 3.82±0.82) for females and 0.61in October 2013 and 2.90 in May 2013 (mean 1.70±0.26) for males. The seasonal growth waspronounced probably due to reproduction activity which extended investment of energy inreproduction causing slower growth. The GSI development was related to photoperiod and themonthly variations of GSI values indicating that the intensive spawning occurred between April2013 and August 2013. During spawning time, the mean GSI value of females (6.04±1.18) was2.9 times higher than the mean GSI values of males (2.08±0.42) (P< 0.05). The results of thisstudy were offered as biological input parameters regarded as a reference for the conservationand management of the Black Sea stocks of the black goby.
